Sneha Ravisankar

• Involves emission evolution modeling for axial turbine of the Hybrid Engine Configuration, developed as part of the joint EU project - AHEAD
• Study on combined effects of heat transfer, aero-thermodynamics and chemical kinetics on exhaust gas evolution in a turbine stage
• Research by Chemical Reactor Network modeling using Cantera, and CFD modeling using Ansys Fluent
• Prospective end - September/October 2019

• Responsiblities - Optimization of the process flow and parameters of the plasma spray coating of fan disk of CFM56-5B turbofan engine
• Optimization done using Design of Experiments and Taguchi-based Grey relational analysis
• Accomplishments - Optimization validated with exceptional results of confirmation tests. Later implemented in the production with expected projections of savings upto $20k per annum

• Aimed at building a WHR unit for the GE90  turbofan engine in Dymola Modeling Software
• WHR unit operating with R245fa was built based on engine specifications and design requirements
• WHR design was optimized for pinch-point temperature difference, leading to reduced Overall Engine Weight and Specific Fuel Consumption

• Optimization of wing planform and its airfoil shape for A330-300 aircraft
• Optimization for aerodynamics, structure and performance
• MDF Gauss-Siedel iteration using fmincon of Matlab was performed using the Breguet-Range equation

• Trim conditions for a conventional and a coxial rotor systems by solving coupled, non-linear 14 system of equations using Matlab and Mathematica
• Team Leader - for a group of 4. Facilitated understanding of problem statement, coordinated and worked with the team to accomplish all the deliverables on time 

• Holistic training leading to understanding of different production stages - design, manufacturing and testing
• Was a part of the testing and certification group and estimated the acceptability of certain parts

A foundation which brings out the creative involvement of the mentally challenged in drama and theatrical performances

• Heat sensing and control in combustion chamber - made a prototype of a control system intended to sense heat in combustion chambers and maintain it within allowable limits
• Ultrasonic Walking Aid for the blind - built an Arduino supported circuit using ultrasonic sensors to sense obstruction and send signals
• Centrifugal shaker - constructed a rotating unbalanced system which can be used for determining natural frequencies
